Be itknownlthat, WILLIAM Gnus, Jr., a i

I 'citizen .of the United:'-States,kl residing at Chicago, in the county or-Coekand State of Illinois,haveinvented certain new and useful improvements in Spring-Leaf -llrubrical tors, of yvhichfthe` following is a specifica- This` invention relates-to lubrication of automobile leaf springs, and the like, by in-V troducing a lubricant from both sides of the spring at the edges thereof.. The principal I object of the invention is to provide a novel construction, `combination and arrangement of parts for accomplishing this result. In the draWi-ngsHFigure l is aside eleva` ation of a portion of a leaf spring with a lubri cator constructed in accordance with the principleslofthis invention applied thereto; Fig. 2 is a sectional view tali-en onthe line 2--2 of Fig. l.; Fig. 3 is a'view looking at the bottom of the lubricator Without the` spring inserted; Fig.'iL shows `a modification oa lubricating element with a groove therein;

A. 7 and the leaves 6. ln fact, the device and'liig. 5 isr e. modification of the lubricating element having a'slot extending over thetop .and sides-` s A satisfactory method of oiling the leaves of a spring is to introducethe lubricant from both sides of the spring at the edges of the leaves thereof. AThe present invention relates to a-device for satisfactorily accomplishing this result. y

A spring of the class to which this inven tion is applied comprises a plurality of sepa'- rate superposed leaves 6 which are held together in any suitable manner with a lubricating device applied to the spring prefer- Iably ata slight distance from the place Where the leaves are rigidlyattached 'tO-, gether. This Alubricator comprises a single member 7, preferably 'Ll-shaped in ,construction, with sides 8 .which extend down over the sides of ya leaf spring and with periorations at the bottom throughfvvhich a bolt 9 may be inserted. i'or fastening the device tol the spring. inserted between the U-shaped member 7 and the spring is a singlestrip or piece of fabric or absorbent material 10, preferably felt or some similar'substance, which 'entirely tills the space between the members l -vvith the lubricating` material inserted fits' snugly over the spring so that it may be Speccationof'. .application nledune 7,1915.

neeessary'to slightly compress the lubricat- 55 ing material to properly liold'- the lubricating device in place by means of a bolt 9.

At the `top of the member 7 is a lubricating cup il with a lid or top 12 which may be raised, as shown in dotted outline'in Fig. 60 y 2,-to insert a vlubricant therein. Depending 'from the sides of the top portion of this member 7`are a number of bendable clips 13, preferably two on each side, which may be .bentover the lubricating material for .65 holding it in place Whentlie lubricating de- 4vice is not applied to a spring andfor assistance' in holding the material in place when the lubricating device is applied to a spring. vIt' desiredpthese clips 18 may be 'I bent from a fiange 14 on each side ofthel To assist in `1 holding the lubricating material 10 in place, the edges of the depending sides 8 may also be formed with flanges 14 which may ter- 75 minate near the end of eachfside 8, the iianges being of less thickness than thematerial 10 so that they will not'interfere with the compression 'of the material or of the sides when the device is applied to a spring. To also assist in holding the lubricating material 10 in place the extremities are formed with perforations 15, as clearly shown in Figs-4 and 5, whiclrconform in shape to the extremities ofthe depending sides 8, as

shown in Fig. l.'

l' `chamber' at the top of the device by forming the lubricating material 10 With-a slot 0r perforation 1G, as shown in Figs. 2 and 3 90 whichcommunicates' directlyv` With the oil cup 1l and formstherewith a receptacle for a small quantity. of Ilubricating material. Instead of making this a perforation entirely `through the lubricating materiali() a groove 95- 17 `may bevprovided, as shovvn Fig. 4,' which extends from the top toward-"`the extremities of Ythe material l0,VY terminating, however, at a distance from theendsthe'reof.'

f Another construction comprising a slot 18, as

shown by Fig. 5, is similar' to that shown in Fig. 4t. comsisting of a slot entirely through the material 10 instead of a groove, as shown in Fig. d. i

When this lubricatoris applied to a spring vit is necessary only to insert the lubricant through the oil .cup l1 and the lubricant is f directed or applied to theedges of the leaves tion and the sliding movement of the leaves with respect to each other. The device is easily applied or removed by 'means of the bolt 9, and the clips 18 hold the lubricating material in place whether the device is applied to a leaf spring 0r not.

lt should be understood, of course, that although this device is intended to be used with the oil cap 1l at the top side of a spring, it could be applied to a spring from the bottom side, in which case the absorbent material would act as a wielr drawing the lubricant by capillary attraction from the bottom to the sides and edges of the leaves of the spring, the bolt 9 being fastened on top of the spring.
